Millennia is a historical turn-based 4X strategy game about guiding a nation across ten ages, spanning humanity’s beginnings to possible futures. Rather than following one fixed historical timeline, each playthrough can take a different course: meet certain objectives and the world may enter a Variant Age, where new rules, technologies, and units reshape the choices ahead. Crises can also steer history toward war, sickness, or ignorance, making the consequences of a nation’s path central to its story.
The strategic work reaches from city growth to the movement of goods across an empire. Players gather food, wealth, and production, then turn basic resources into more valuable products through research and improvements. Regions can specialize, and surplus goods can be shipped where they are needed, linking distant colonies and industrial centers. Research also unlocks units, buildings, and improvements, while Nations Spirits let a civilization develop a distinctive identity, from warrior or explorer traditions to cultural or financial influence.
The supplied store categories identify Millennia as single-player as well as multi-player, with PvP and online PvP listed.
